ELEMENTS TO BE ASSESSED
Further guidance on this issue is contained in ICAO Circular 305-AN/177 and ICAO Circular 301-
AN/174.
In any case, the elements that have to be taken into account for the safety assessment are, without
prejudice to other assessments that may have to be conducted, in accordance with other applicable
requirements contained in Part-ADR.OPS.
Such assessments should include, but are not limited to:
(a) the aircraft mass, tire pressure and ACN values — with regard to overload operations;
and
(b) maximum passenger and fuel carrying capacity — with regard to level of RFFS protection
to be provided and the aerodrome emergency planning.
SUBPART C AERODROME MAINTENANCE (ADR.OPS.C)
Reference Description
ADR.OPS.C.005 General
The aerodrome operator shall establish and implement a maintenance programme, including
preventive maintenance where appropriate, to maintain aerodrome facilities so that they comply with
the essential requirements set in Annex Va to Regulation (EC) No 216/2008.
ADR.OPS.C.005 AMC1 General
MAINTENANCE PROGRAMME
The aerodrome operator should ensure that a maintenance programme is established and
implemented, including preventive maintenance where appropriate, to maintain aerodrome facilities in
a condition which does not impair the safety of aeronautical operations. The scope of the
maintenance programme should include, but may not be limited to, the following items:
(a) visual aids and other lighting systems required for the safety of aerodrome operations;
(b) power supply and other electrical systems;
(c) pavements, other ground surfaces, and drainage systems;
(d) fencing and other access control devices;
(e) equipment and vehicles, including those used by rescue and firefighting services, which
are necessary for the safety of aerodrome operations; and
(f) buildings which are necessary for the safety of aerodrome operations.
ADR.OPS.C.005 GM1 General
HUMAN FACTORS
The design and application of the maintenance programme should observe human factors principles.
ADR.OPS.C.010 Pavements, other ground surfaces and drainage
(a) The aerodrome operator shall inspect the surfaces of all movement areas including
pavements (runways, taxiways and aprons), adjacent areas and drainage to regularly
assess their condition as part of an aerodrome preventive and corrective maintenance
programme.
(b) The aerodrome operator shall:
(1) maintain the surfaces of all movement areas with the objective of avoiding and
eliminating any loose object/debris that might cause damage to aircraft or impair
the operation of aircraft systems;
(2) maintain the surface of runways, taxiways and aprons in order to prevent the
formation of harmful irregularities;
(3) take corrective maintenance action when the friction characteristics for either the
entire runway or a portion thereof, when uncontaminated, are below a minimum
friction level. The frequency of these measurements shall be sufficient to determine
the trend of the surface friction characteristics of the runway.
ADR.OPS.C.010 AMC1 Pavements, other ground surfaces, and drainage
GENERAL
(a) The aerodrome operator should maintain the surface of a paved runway in a condition so
as to provide good friction characteristics and low rolling resistance. Mud, dust, sand, oil,
rubber deposits, and other pollutants should be removed, as rapidly and completely as
possible, to minimise accumulation.
(b) Taxiways and aprons should be kept clear of pollutants to the extent necessary to enable
aircraft to be taxied to and from an operational runway.
(c) Drainage systems and storm water collection systems should be periodically checked
and, if necessary cleaned or maintained, to ensure efficient water run-off.
(d) The aerodrome operator should measure the runway surface friction characteristics for
maintenance purpose with a continuous friction measuring device using self-wetting
features. The frequency of these measurements should be sufficient to determine the
trend of the surface friction characteristics of the runway.
(e) The aerodrome operator should take corrective maintenance action to prevent the runway
